IMPROVEMENT IN LAMP-BURNERS.

Specification forming part of Letters Patent No. 169,161, dated October 26, 1875; application filed July 31, 1875.

To all whom it may concern:

Be it known that 1, JOHN H. FOUCH, of Sank Centre, Stearns county, Minnesota, have invented a new and Improved Lamp-Burner, of which the following is a specification:

Figure 1 represents aside elevation, and Fig. 2 a vertical central section, of my improved lamp-burner.

Similar letters of reference indicate corresponding parts.

My invention relates to an improved burner for gasoline and other lamps, by which the flame may be regulated in a simple and effective'ma-nner, producing a greater or less amount of heat without waste of gas. The invention consists in combining with a wick-tube an inclosingshell or cut-oft tube, the latter being adjustable on the former, and the arrangement of gas-orifices being such that a portion of the jets may be closed without closing the others, as hereinafter described.

In the drawing, A represents the main burner of a gasoline or other-lam p, which is open at the top, and provided with a number of gas-issuing holes, a, that are at a suitable distance from each other and from the end of the burner. A shell. or cut-oft, B, .fits on the burner, and is provided at the lower end with a butignited gas-jets and amount of light emitted therefrom may be easily regulated.

I do not claim a burner composed of two coincident tubes, of which the outer one is adapted to cut off the emission of the inner; but

I claim- The combination of the inner tube B, having the gas-jet holes I) and the inclosing-tube B, having corresponding slots (1, one larger or wider than the other, to operate as and for the purpose specified.
